Quartz is the rock known under the name of el Marw. It is named after the metal that makes it to signify its blocking nature. The bigger part of it is used in the production of iron ingots (ferrosilicon ingot). The ground material is used in the making of ceramics, but as for the transparent quartz, it is used for electronic purposes and radar as well as optics since certain types of it produce lenses, slices and light prisms. The chemical composition of quartz includes silicon dioxide, which is the most common metal in igneous rocks and it gains its economic value when found in amounts of highly fine conditions.
